I attempted to install kali dual-booted on my Mac. The install was successful... until I couldn't access my partition after re-entering my OS X system. I've attempted to install rEFInd. It won't work. I try holding the option key at boot, kali won't show up. I have no idea how to access my machine. Apples SIP seems to be the issue. I have tried a lot of different methods to set Kali as my default boot OS, but the message I'm getting when I try and set it with 'bless -setBoot' says that Mac does not recognize the file system. Any ideas? Can I change the boot order from a live USB or install rEFInd from a live usb? thanks.
